Mb. Scharf et al., COMPARATIVE EFFECTS OF SLEEP ON A STANDARD MATTRESS TO AN EXPERIMENTAL FOAM SURFACE ON SLEEP ARCHITECTURE AND CAP RATES, Sleep, 20(12), 1997, pp. 1197-1200
The comparative effects of sleep patterns and rates of cyclic alternat
ing patterns (CAP rate) in a high quality innerspring mattress were co
mpared to those on a unique foam support mattress in 10 normal subject
s. Results showed no differences in sleep stages, number of wakes, or
total sleep time between the two conditions. CAP rates were significan
tly reduced on the foam surface. CAP rate was sensitive to the first-n
ight effect on both surfaces, but was blunted on the foam mattress.
